Oil Stain In Leather

Using Cosmoline between two layers of leather sounds a bit bizarre to me.. Unless the leather is sealed before applying the Cosmoline then it's bound to start seeping through when it gets warm/hot, being a grease. I'm trying to visualise a reason for doing it and can't for the life of me think of one.

And if you find a process for drawing the Cosmoline out of the leather then what is the point of putting it there in the first place?

I guess the best way i can describe it is it works as a moveable adhesive. I know it sounds odd to use but that is the way they have done it for the last 90 years, while trying to get them to move to a different product im also trying to find a way to salvage ones that have been stained if possible

Yes, it does sound odd. After 90 years you would think they would have found something better that doesn't have the potential for staining the items (whatever they are).

I know what will take the cosmoline out, but it is going to take the leather dye & everything else that's been applied to it, finish wise.

Anything that can dissolve grease is bound to be a pretty strong (nasty?) solvent.......

A pair of scissors will remove any oil stains on leather, especially  Cosmoline stains

Why not toss the cosmoline and use elmers white glue . . . or rubber cement.

Both will allow for a certain amount of movement while you are sewing the product . . . and since you are sewing it . . . it is to at some point . . .  be prevented from movement.

Both the white glue and rubber cement will give you that option . . .  and unless you practically bathe it in the glue . . . it will not come thru.

Try a couple pieces . . . I think you will like it as an option.

And just as an ending note  . . .   if anyone came into my leather shop with cosmoline . . . they would promptly shown the door and their product would go with them.  That is almost like hiring the wolves to guard the sheep while I go on vacation.

May God bless,
